Hello,

My customer have a question about TPS65910.

I do not know the difference for the following .

There is a description on the datasheet and product page.

=============================================================================

Datasheet

5.2 Handling Rating

Storage temperature range -45℃～＋150℃

5.3 Recommend Operationg condition

Storage temperature range -65℃～＋150℃

Product page

(www.ti.com/.../TPS65910

Parametrics

Operating Temperature Range (C) -40 to 85

What these differences?

I'm looking forward to reply from you

Best regards,

Watanabe-san,

Apparently -45 to 150 in this context can be considered the Absolute Max Ratings for the Functional Junction Temperature.

The device can be stored from -65 to 150 according to the ROC.
The device was tested from -40 to 85 for the specifications.

Best Regards,
Rick S.

Dear Richard,

Sorry to bother you so often.
I forgot to mention one thing.

I understand ROC means Recommended Operating Conditions.

If it is within the ROC range,The device can be stored from -65 to 150.
Is this understanding of mine correct?

Best regards,
Watanabe.

Correct,
The device will meet the datasheet specifications while exposed to the same operating free-air temperatures that it was tested in. The package itself can withstand the storage temperatures listed, but the device may not operate within spec while exposed to these more extreme temperatures.
